To reduce installation space as well as weight, the use of shape memory alloys (SMA) is advantageous in the field of actuator technology. A big challenge using SMAs in for actuation is their high energy consumption due to Joule heating. To overcome this, an actuator system based on the agonist-antagonist principle, using SMA wire actuators was developed. Main advantage is the possibility of an energy-free holding of the position without the use of special locking components.

A big challenge using SMAs in for actuation is their high energy consumption due to Joule heating. To overcome this, an actuator system based on the agonist-antagonist principle, using SMA wire actuators was developed. Main advantage is the possibility of an energy-free holding of the position without the use of special locking components. A prototype made of CFRP and SMA wires was developed and built. The structure consists of a CFRP laminate on which SMA wires are anchored on the upper and lower side. This work also contents a simulation approach of the actuating structure in ABAQUS® using a simplified phenomenological model. » weiterlesen» einklappen
